Comments "HIV-1 RT isolated from virions is a heterodimer consisting of two polypeptide chains [5,6]. The 66-kDa subunit (p66) contains the amino acid residues responsible for both the polymerase and RNase H activities. The 51-kDa subunit (p51) whose amino acid sequence is identical to the N-terminal portion of the p66 subunit exhibits neither enzymatic activity in the heterodimer [primary sources]."
